NUT-LOCK."

To all to hom it may concern:

- Be it known that I, C Y E C. WVILLI Ms, a a

citizen of the United States, residing at Guymon, in the county of Texas and State of Oklahoma, have invented certain new anduseful Improvements in Nut-Locks, of which the following is a specification.

This invention relates to improvements in nut locks. v

The main object of the invention is to provide a nut lock having an improved construction and arrangement of locking mechanism adapted to securely fasten the nut in its adjusted positions on the bolt and which may be readily released to permit the nut to be removed.

Another object is to provide a nut lock which will be simple, strong, durable and inexpensive in construction, efficient and reliable in operation and well adaptedto the purpose for which itis designed.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention-resides in the combination and arrangement of partsand in the details of construction hereinafter described and claimed, it ,being understoodthat changes in the precise embodimentof set screw and its cooperating catch, and

Fig. 5 1s a similar view of the catch detached.

In the embodiment illustrated, a bolt B of usual construction is shown on which is adapted to be mounted a nut 1 having one corner beveled as shown at 2. A bore 3 extends obliquely through this beveled corner portion and communicates with a bore 1 which receives the bolt B as is shown clearly in Fig. 2. The bore 3 is threaded to receive a set screw 10 and its outer end registers with a seat 5 designed to receive the head 11 of the set screw. Radiating from the seat Specification of Letters'latent.

5 are a plurality' of grooves or} notches 6;, adapted to receive a catch 12 carried by 'the'.

set screw 10, when the set screw is" inlo le ing position as shown in Fig. 2. The screw 10 has the usual kerf 13 in its head for the receptionof a screw driver and extending at rightangles'from said kerfis a groove;

ll in which is pivotally mounted the locking catch 12; This catch 12 is in theform of tongue 14" which is designed to rest on the: bottom of the kerf .13 and operates normally,

to hold theouterend of the catch in locklng engagement withone of the notches 6 formed in thenut face 2. This spring tongue 14" is'yieldable under pres sureeX ertedbythe insertion of a screw driver in the kerf 13 as is shown indottedlines Fig, 2and causes said catch to be tilted on said in Fig. 2 thereby releasing the catch from the notch 6 with which; it isengagedto permit the screw 10 to be moved.

In the use of this improved nut lock, the screw 12 may be partially inserted in the bore 3 and the nut 1 screwed on to the bolt B until it reaches the desired position. The screw 10 is then moved inwardly by means of a screw driver inserted in the kerf 13, the insertion of which operates to hold the catch 12 with its outer end swung outwardly so that the screw may be screwed home into operative position without said catch-interfering with its turning. After the screw has been moved inwardly to bring its point into biting engagement with the bolt B as shown in Fig. 2, the removal of the screw driver will permit the catch 12 to swing downwardly into locking engagement with one of the notches 6 as shown in full lines Patented Nov. 26,1918.

. fee a bar which is pivoted intermediately of its.

8O insertion into the dotted line position shown in Fig. 2. It will thus be seen that the to be moved outwardly a suflicient distance to disengage its point from the bolt and thus permit the nut to be unscrewed in the usual that such changes may be made as are with in the scope of the claimed invention.

I claim 1. The combination with a nut having a bolt receiving bore and another bore com.- municating therewith and extending at an angle thereto, a set screw operable in said second bore, and cooperating elements carried by said nut and screw for locking the latter in operative position said elements being releasable by the engagement of a screw driver with the screw.

2. The combination with a nut having a bolt receiving bore and another bore communicating therewith and extending at an oblique angle thereto a seat surrounding the outer end of said second bore and provided with a plurality of radially extending notches communicating therewith, a set screw for insertion. in said second bore having a head provided with a kert adapted to be positioned in said seat, when the screw is in operative position, a latch pivotally mounted on said screw head intermediately of its ends with one end intersecting said. kerf and its other end projecting beyond the perimeter of said head and adapted to engage one of the notches radiating from the seat in the nut when the screw is in operative position.

3. l'he combination with a nut having a bolt receiving bore and another bore communicating therewith and extending at an oblique angle thereto, a seat surrounding the outer end of said second bore and provided with. a plurality oi radially extending notches communicating therewith a set screw for insertion in said second bore having a head provided with a lrerf adapted to be positioned in said seat, when the screw in operative position, a latch pivotally mounted on said screw head intermediately of its ends with one end. intersecting said kerf and its other end projecting beyond the perimeter of said head and adapted to engage one of the notches radiating from the seat in the nut when the screw is in operative position, said. catch being provided at its inner end with a spring tongue positioned to yieldably hold the catch in locking position.

In testimony whereof I affiX my signature in presence of two witnesses.
